Answer:
Step-by-step explanation:
1) Isosceles triangle
2) Right angled triangle
3) Scalene triangle
4) Equilateral triangle
5) Right angled triangle
6) Scalene triangle
7) Equilateral triangle
8) Scalene triangle
9) a) Equilateral triangle
9) b) Scalene triangle
9) c) Isosceles triangle
9) d) Right angled triangle
Note: Right angled triangle - If one angle is right angle, then it is Right angled triangle
Isosceles triangle: If two angles or two sides are equal, then it is Isosceles triangle.
Scalene triangle: If all three sides or three angles have different measurement, then it is Scalene triangle.
Equilateral triangle: If all the three sides are equal or all the three angles are equal, then it is Equilateral triangle
1 3/6 + 4/6 = 1 7/6 = 2 1/6
The denominator in each term of the series is a square number, but neither

nor

are squares. So none of (1), (2), and (4) can be correct. The answer must be (3).
Well I really don’t know but good luck w this I hope you pass school is so stressful
It would be 13 becsue 12.5 time 2 = 25 so round that it = 13
